T0 at whom it may concern.-

Be it known that I, ELIE GAUCHER, a citizen of the Republic of France,and a resident of Constantinople, Turkey, have invented certain new anduseful Improvements in or Relating to Compressed-Air-Operated WaterRaising or Forcing Apparatus, of which the following is a specification.

This invention relates to apparatus for raising or forcing water bymeans of compressed air.

The apparatus occupies very little space, is very simple, and at thesame time of strong construction, scarcely ever requiring any repairs,though when required they can be effected very easily.

Apparatus according to this invention is illustrated by way of examplein the accompanying drawings, in which Figure 1 shows the Wholeapparatus in a perspective view. Figs. 2 and 3 are views showing theapplication to the apparatus of two different systems of valve-gear forthe compressed-air supply. Fig. 4 is a vertical section, on a largerscale, of the valve mechanism shown in Fig. 2. Fig. 5 is a side view,and Fig. 6 a sectional view, representing in detail the manner ofmounting the balance lever or hammer on the plate.

The apparatus com prises a receptacle (1., consisting of two parts, acasing and a base, connected in an air-tight manner by bolts. Thisreceptacle is placed in the water to be pumped, which can enter itthrough a pipe I), provided with a strainer 0 and a non-return valve d.An outlet-pipe 6, provided with a check-valve f, communicates with thesaid receptacle, and a third pipe 9 admits compressed air from anysuitable source of supply and through a suitable tube, as 28. Thereceptacle contains a float h, secured by arms to a spindle 2', passingthrough one or both of the walls in stuifing-boxes, insuring a tightjoint. At the outer end of the spindle z' is mounted a double-armedlever f. To each end of the lever j is pivoted a rod is, the upperportion of which is connected to another double-armed lever Z, securedto a horizontally-mounted spindle m. The spindle m is furnished with twoprojections, as m, which enter openings in plate 4 Serial No. 198,238.(No model.)

and are retained by nuts, as at m applied on their extremities. The twoconnecting-rods are provided with adjusting-screws a n.

The whole of the parts described constitutes the first part of theapparatus. The second part is arranged on a table or any other suitablesupport, such as o. To this support is fixed a board 2, carrying twouprights q q. The distance between the uprights is maintained constantby means of two top crossbars 1" r, between which is supported athreeway cock t, the plug of which is extended in the form of a spindles, mounted on the uprights This cock is connected to the pipe g andestablishes communication in one of its positions between a pipe u,opening into the atmosphere, and the pipe g. By means of this cook thecompressed air reservoir is placed in communication with the receptaclea and the receptacle a with the atmosphere.

In order to control or operate the clock 23, the spindle s has securedto it a small depending rod o,which passes between two rods 00 w, asshown in Fig. 1, or into a recess in an oscillating lever or partsecured to a spindle s. The oscillation of this lever is caused by theoperation of a balance lever or hammer 2. This hammer is composed of ahollow curved cylinder closed at both ends and provided at both endswith projecting strikers w w,which, according to the position of thecylinder, strike the right or the left hand side of the lever y,and somove it to one side or the other.

In the hollow cylinder is arranged a ball Z, which rolls in the cylinderin accordance with its inclination. This hammer is secured by means oftwo supporting-rods 2 2 to a block 3, arranged astride the spindle m. Tothe spindle is secured a board 4, on which are provided two projections5 5. The board 4 turns with the spindle, and in its oscillations one orother of its projections 5 5 raises the hammer 2. On the stationaryboard p are two other projections 6 6 of sufficient height in order thatwhen the hammer descends the ball Z should come to lie in the angleformed by the central part of the cylinder and one of the inclined endparts.

The three-way cock can be advantageously arranged in vertical position,as shown in Fig.

3. It can be operated in that case by toothed wheels, such asbevel-gears 7 and 8, mounted, respectively, on the spindle s and on thespindle of the plug of the cock. The cock 2? could also be replaced by avalve-box 9, Fig. 2, in which the valves are actuated by theoscillations of the lever 1 through an intermediate connectingrod 10 ofsuitable shape, pivoted to a crank 11, mounted on one of the ends of thespindle s. This valve-box is constituted by a central casing 12, Fig. 4,having mounted on it valves 13 and 14: and containing a lever or beam15, pivoted on a spindle 16, mounted in two lateral plates 17, connectedby bolts 18 and surrounding the casing 12, so as to form with it anair-tight box. The bolts 18 also secure the box to the upright q. The

inlet-valve 13 for compressed air is connected to the beam 15 by a smallrod 19 and is, moreover, provided with a spring 20, having the tendencyof maintaining it applied against its seat.

The exhaust-valve 14 is provided at one end with arod 21,freely restingagainst the bottom of a recess made in the beam 15, and at the other endwith a guide-rod 22, pivoted to the connecting-rod 10, Fig. 2. A coiledspring 23, surrounding the rod 21, has the tendency to always maintainthe valve 14 against its seat. A spring 24:, stronger than the spring28, exercises at the opposite end of the beam 15 a permanent pressurehaving the tendency to open the valve 13,and consequently to close thevalve 1 1. A pipe 25 opening into the chamber of the valve 13 admitscompressed air, which when the position of the valves is favorable isadmitted into the receptacle a through the pipe 26. A pipe 27 openinginto the atmosphere enables the air from the receptacle a to escapewhile it is being filled with water-that is to say,when the beam 13occupies the position shown in Fig. 4.

The working of the apparatus is as follows: Assuming that the float ithas been brought to its highest position by water filling the receptaclea, at that moment the cock 2? will be in communication with thecompressed air reservoir through the pipe 25 and with the receptacle athrough the pipe 9. The valve (Z,

opening from the outside inward, is automatically closed by the pressureof the compressed air, and the water being unable to es cape through thepipe 6 will rise in the pipe 6. The level of water in the receptacle (4therefore sinks. The float h descends and turns the spindle i, which bymeans of the connecting-rods 7c and the lever Zcommunicates its movementto the spindle m. Thelatter spindle causes the board 4 to oscillate. Oneof its projections 5 raises the hammer, and the ball 1 under theinfluence of gravity rolls along the interior of the hammer and bringsabout the completion of the stroke of the hammer z. The latter by meansof the striker w causes the lever 3/ to oscillate, and thus pro ducesrotation of the plug of the cock t, which assumes the position requiredfor establishing communication between the receptacle (0 and theatmosphere or for actuating the valvegear, as already described. Theweight of the Water outside the receptacle opens the valve d when thecounter-pressure of the compressed air ceases. The valve f closes by theweight of water above it, and the receptacle is again filled with water,and the float it rises. Similar movements to those already describedthen take place, but in the opposite direction. The cock tis returned toits original position, and the same movements take place alternately.

This apparatus can be made very small or as large as may be required.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. A compressed-air-operated water raising or forcingapparatus comprising a closed receptacle having a compressed-air inlet awater-inlet and a water-outlet, a float therein operating a spindleprojecting outside the wall of said receptacle a lever device connectedthereto and operating a spindle carrying a balance-striking device, alever operated thereby and a valve operated by said lever to alternatelyconnect the float-receptacle with the compressed-air supply and theatmosphere, substantially as described.

2. In a water raising or forcing apparatus of the kind described apivoted valve-operating hammer composed of a hollow cylinder withupwardly-bent ends and carrying striker-arms at each end and a balladapted to roll in said cylinder and complete the stroke thereof by itsweight, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
